I find this a very useful article in spelling out the connections between Marx and anarchism, although there is a branch of anarchism that is more liberal/entrepreneurial that collectivist - but the critique of ideology is important to Marx, and any Utopia must not disavow that, and must remain alive to its own potential for power exploitation and dominance. A Utopian perspective with a practical focus is Utopia and Organization, co-edited by Martin Parker, whose other work is worth attention, as is the work of his colleague Chris Land. The more liberal take is wonderfully outlined in Pierre Guillet de Monthoux's Action and Existence, and also his The Moral Philosophy of Management : from Quesnay to Keynes. Turning to Foucault, it's de Botton who accused him of seeking to create a "Marxist-anarchist utopia" and that's covered here http://www.openculture.com/2015/07/an-animated-introduction-to-michel-foucault-philosopher-of-power.html if a bit populist. Foucault's idea of a "heterotopia" is probably what de Botton is caricaturing but it needs to be taken seriously - here's Foucault setting out its principles and distinctions, though there are plenty of other sources. https://www.google.co.uk/url?sa=t&source=web&rct=j&url=http://web.mit.edu/allanmc/www/foucault1.pdf&ved=0ahUKEwiN8PaztHMAhWFZj4KHTGlBAoQFggwMAM&usg=AFQjCNGyuaZMuCRKdw_-gZ2FuQ0Fo5idog&sig2=zTbua31eIl7g2xloKcbCzw
